10 minutes into the LBJ job and this happens...

This where an impact wrench comes in handy. It doesnt shear the bolts like just torqueing with a breaker bar.

The problem is that it's hard to get an impact wrench under that with regular jack and stands. I could not and had to trust my penetrating oil.

I bought an impact wrench specifically for this, but the bolts weren't budging. That's when I switched to a breaker bar. It lived up to its name.

This one can remove the bolts quite well all day long...

Can of coke works just as good believe it or not.

False.
Compared to WD40, maybe. There is a reason Kroil is $17/can.
When you soak a bearing in PB blaster for a day, then break a 20 ton 3 jaw puller, you start to invest in the good stuff.
You know when you work on the big, expensive stuff...

The 50/50 acetone/atf does work amazing, plus it's dirt cheap. I bought one of the cans you can pressurize with whatever you put in it. You just have to shake it up before using it because the two liquid do like to separate.

Can really post of pic of the big heavy stuff I work on . But don't count the coke out till you try it... when you in the middle of now where and supply is out of penetrating oil you got to use what you have.

There are some really nice cordless impact wrenches nowadays - some of them are pricey, but there are some bang for buck examples like the dewalt shown above. Milwaukee's brushless "Fuel" stuff is also excellent. I haven't run across a bolt it can't take off. The big one I have says it can apply 1200 lb/ft loosening force.

Also recommend this set:

It has a little joint that you can stick before or after the extension, depending on space and angle, plus, the sockets fit very well on fasteners. For the price, it's a great set.

I remember when I did LBJs deep sockets didn't really have the clearance, but the standard depth ones did with an extension.

With all the good information in here I might revisit this. I had already dropped more than 200 bucks into tools for this job though so I can't imagine a shop costing much more than that for labor. I'll ask around.

Raise the jack up a bit with a couple nice 2x10s and of course secure it with stands. Worked great for me! :cowboy:

Bummer. Hate it when that stuff happens.

 

[johnbyebye]

I am giving this another shot this weekend. I purchased some Kroil and will try the ATF + Acetone mix as well. I went back to Home Depot and bought another impact wrench. It was actually cheaper this time. Lol.

 

[johnbyebye]

I finally got this done. I was still unable to get the broken bolt out so I'm taking it to a shop next week but at least everything else is done.

A can of Kroil made this a sinch. I was quite impressed by it so thanks for recommending that.

cordless impacts really suck at loosening out larger rusty bolts. You would be better off investing in a 5 gallon compressor and some basic air tools for those kind of jobs if you want to stay on the low budget

My $99 Ryobi did just fine for this job. I wasn't gonna spend too much for a tool I'd rarely use.

 

[LittleCaesar]

Good to hear. Kroil is expensive as heck in comparison to other penetrating lubricants but has no competition for being the best IMHO.

I can't speak for all cordless impacts, but I've done the suspension on my truck, suspension on the Porsche, crankshaft bolt, fan bolt on the Porsche and a large number of other odd jobs, and the thing never broke a sweat. But yeah, air tools are better, I guess?

A 'live and learn' thing, I guess, but always use penetrating oil for a few days (preferably weeks) in advance on any bolt you plan on loosening, regardless of where you live.
Obviously, the stronger stuff will work better in a 'quick pinch' situation, but WD-40/PB-Blaster, etc work fine if you give them a few days with multiple applications.
I live in rust free Texas, but 3 applications of PB-Blaster during the week leading up to the jobs, I was able to remove my stock LBJ and Upper Rear Shock bolts so easily I thought at first that they were either not torqued down AT ALL, or they were already stripped.
Made the jobs extremely easy, and there are multiple threads solely on how to remove the shock bolts because they are supposed to be so hard.

 

[Scramble]

I'm cheap so I use WD40 a week before & then the night before. All 8 bolts came out easily with an impact & I live in the rust belt. My LBJ's had 153,000 when I changed them.

IMO my first mistake was trying to use a breaker bar on it. Only half the bolt is actually threaded into the mount. The other half just passes through the LBJ.

One more thing to what Scramble said "remove the rust on the exposed threads"
